I'm Cute And Manly, And I'm Starting To Get Swamped. I Am Drowned In My Nephew Who Is A Virgin, Body And Soul. Yurika Aoi

Yurika is a housewife with a husband and son. Her nurse sister asks her to look after her high school student son Shun's dinner on night shifts, so Shun often comes to Yurika's house... Her nephew, whom she hasn't seen in a while, combines the same brashness from childhood with a manly reliability... Watching him eat her home cooking deliciously and his suggestive words stir feelings beyond maternal instinct in Yurika. Then, on the night her husband's affair is discovered, Yurika is swayed by Shun's concern, and the two cross the line.
